Reload a modified file in SNAP

Hi, I am doing some experiments that need to frequently modify/update a .dim file using Gpt. After each run, I need to view the result in SNAP.

Currently I notice the opened .dim file in SNAP does not update itself, after modified its file. Therefore, I will need to reopen a new instance of the same file. It is quite a pain to open the exact same file after each run, not mention the confusion of many instances of the file opened in the SNAP.

Is there some better solution to quickly reload/update a file loaded in the SNAP, without reopen it?
